They did both my house and a rental we have that is currently occupied with tenants. 

Conventional loans require 15% down on an owner occupied duplex.  

One unit was vacant (which I could occupy for my loan).

However in my findings and talking with attorneys AB 1482 clearly allows for the owner to serve just cause termination with owner intent to occupy. section (e)(8) is a little confusing reguarding the ownership of the property not being held in a LLC or trust, but as I do not have a LLC it looks like I am able to serve notice to one of the units and move into it which I plan to do.  60 day notice and relocation assistance equal to one months rent. 

Hello,So I am buying a small MF 2 doors (this is my fist property), both occupied with tenants one is on a lease and the other is tenant at will. 

I would NOT be able to satisfy the second home criteria to occupy it for a month atleast in a year. 

Or are they assuming that the home is already occupied and want a copy of the current lease?

If you're looking to house hack, you might not need an investment partner as you can get into an owner-occupied home for as low as 3-5% down.

@Evan Swanson The lender required us to buy our first few investment properties in our name and we never hid the fact that they were to be rented out, or that we might occupy during a make-ready. 

Purchase a Multifamily property were you occupy one of the units.
